.l BRICK-HANDLING DEVICE.

Application'alea August 21, 1924. serial No. 733,345.

This invention relates generally to brick making machines and moreparticularly t an improved form of apparatus for handling the bricksafter they have been molded.

The object of the invention is to provide a strong, durable andcomparatively simple machine which will bump the molds at the ends asthey emerge from the pressing machine and then invert the palleted moldl0'so as to deposit the molded bricks upon the pallet and convey themVto the drier while the inverted mold is carried back sanded, reversedand placed in position to receive another charge of clay.

With this main object in view and cer'- tain minor objects which willappear hereinafter the invention consists in the novel features ofconstruction and combination all of which will be fully describedhereinafter and set forth in the appended claims.

Referring to thedrawings, 10 indicates a puc` mill or other type of brick making machinewhich is provided witha 'die 11 at its delivery end for the purpose ofdirecting' the clay into the mold 12Vwhich is arranged beneath the die,said mold resting upon a series of rollers 1 3 journale'd in the mainframe 14, the mold beingfprojected beneath the die 11 by meanshereinafter explained. itis pushed along by the neXt succeedingT moldand while resting between the guides 16 each end of the mold issubjected to a bumping or'haminering by means of a hammer 17 mountedupon one end of a rock shaft 18 which carries an arm 18a which isengaged by the cam 19 mounted upon a shaft 20, the cam causing the armto rock back and forth at definite int-ervals for the purpose ofstriking the end of the mold. This shaft 2O which carries the cam uponthe exterior thereof turns at stated intervals for the purpose of and inthe man` ner hereinafter set forth. y v

The blow of the hammer is adjustable to 'a limited extent, thisadjustment being accomplished by means of a threaded rod 18b having ahand wheeln18B at the Outer end and working upon` this threaded rod isan arm 18C through which is also passed a rod molds over the lowerl CIIpression of the spring 18h fil cams 23 mounted upon a shaft 24 18d andbetween the arm 18C and the end of the rod 18*1 there is a coil spring18h. The outer end of the rod 18d passes through a lug 182 mounted onthe shaft 18 and a knife blade washer 18I is held in contact with thelug 1Se by means of nuts 18g, this knife blade washer permitting therocking movement of the arm which exerts the necessary pressure due tothe position of the arm 1SC and the amountof compression under which thespring 1Sh is placed.

rEhe arm 1S is held in an upright position by a rod 18m which passesthrough a boss 18 on one side of the arm 1S". Ey rotating the rod 18" bythe hand wheel 18B the arm 18C is moved back or forth on the rods18b and18m thus increasing or decreasing the com- Y which will change the blowof the hammer 17.

After the mold has been bumped or knocked, a pallet of metal or wood isplaced upon the bricks contained within the mold. rllhe bumped andpalleted mold is pushed along the table and into an inverter which turnsthrough one-half of a revolution at each`hal't rotation of the shaft 21upon which the inverter is mounted and as the inverter makes one-halfrevolution, it is obvious that the filled and palleted mold will beinverted, that is the pallet being on the bottom and the mold upon thetop, this inversion being due todischarging the bricks from the mold.

The inverter comprises a central portion 22 and similar upper and lowerportions 22a bolted to the central portion 22, the upper and lowerportions being arranged in reverse order as shown so that oppositelydisposed and offset spaces are provided intowhich the filled andpalleted mold is pushed and ejected. The central portion 22 's keyed tothe shaft 21 and working through the shaft 21 and through the centralportion 22 is t-he ejector rod 22b lining ejector' lingers 22c at eachend thereof, these lingers working between the guide shoes 22d, theseshoes being spaced apart just sufficiently to permit the palleted meldto slide freely into and out of the recess. The palleted mold is pushedfrom the table into the upper compartment of the inverter and in doingso, it comes in contact with the finger 22C and pushes the sameinwardly, this movement of the finger 22C forcing the rod 22b throughthe shaft 21 and forcing or ejecting the inverted mold from the oppositeand lower compartment of the inverter.

The pallet and inverted mold are pushed upon thetable 23 which iscarried bv a pair of arms 23, said arms being in turn pivotallyconnected to pair of parallel bars 23b pivoted at 23C and beneath thetable 23 there are mountedV rollers 23d which contact with which shaftis constantly rotated, and the cam 23e is so placed and is of such shapethat the table 23 will be placed directly in line with the lowercompartment of the ejector so that the pallet and mold can be pushed outupon this table 23. Adjacent the ends of the table 23 are providedspaced projecting` portions 23f along which the mold 12 travels and isdischarged onto the endless chains 25 traveling` around sprockets 25amounted upon a shaft 26. T he pallet with the bricks thereon, however,is somewhat shorter than the mold and as the table 23 is lowered due tothe movement of the cam 28e, the pallet with the bricks thereon isdeposited upon the endless chains 27 from which they are directed to theconveyors 28 by means of which the pallets with the bricks thereon arecarried laterally away from the machine as most clearlyv shown in Fig.4. These chains 27 pass around the sprockets 27a upon the shaft 26 and asprocket 27 upon the shaft 24.

lllhile the mold is held upon the table 23 the bottom of the mold istapped by means of hammers 29 arranged upon the ends ef the arms 29,said arms being connected to a shaft 29b and having a linger 29C whichis actuated by a tappet cam 29d to trip the hammer arm and cause thehammers to strike upon the bottom of the moldV in order to morecompletely dislodge the bricks therefrom. ln order to prevent thehammers striking too sharp a blow, l provide a bar 29e entending acrossthe frame and supported upon springs 29f surrounding the rods 29g. Thisspring bar tempers the blow and thereby avoids injury to the mold andlikewise the bricks.

In order to move the mold and pallet along as they are ejected from theinverter, l provide a pair of pusher arms 30 mounted upon stud shafts 31said arms having each a linger portion 31a which is operated upon a camarm 311 rigidly mounted upon the shaft 24:, and this cam arm 31h is soplaced that at the proper point of revolution of the shaft it engagesthe linger 31a moving the pusher arm 30 in the direction indicated andpushing the mold along on the side guides at the same time that thepallet is directed to the table 23.

The chains 25 traveling in the direction of the arrow indicated in 7move along in the mold guides composed of an angle iron and carriv theinverted and empty mold along while. t-he pallet with the bricks thereloon is guided off by the conveyor 2S7 as most clearly shown in Figs. 2and 4;.

The chains 25 travel around the sprockets 25l at one end and sprockets25b at the opposite end, the lower flights of the chains 25 passingbelow thelateral conveyor. Then the mold reaches the end of the moldguide as it passes around the sprockets 251, it is deposited between themolt receiving and lowering arms 33 and 83"* connected to blocks rigidlyattached to a cross shaft 33", ythis cross shaft 33'b carrying arms 33eprovided with rollers which engage cams 33d mounted upon a shaft 34which also carries sprockets 34El and aro-und which travels the moldreturning chain 35, these chains also traveling around sprockets 35nmounted upon a shaft l36 which 'also has 'another set of sprockets 36aaround which travel the chains 37 the purpose of which will appearherein-after.

The mold .is carried down the mold guide 'and delivered to the moldreceiver and lowerer which, as before stated, is actuated and so timedthat it 'receives the empty mold 'and deposits the same upon the'chain`35 traveling` in the direction indicated in Figs. 2 and 7 andfrom the chain 35 it is discharged to the chain 37 traveling in the samedirection, and this chain 37 passes over the top of the sand box 38 inwhicliare mounted the rotary beater arms 38a which stir up the ksand andthrow it upwardly with such force as to thoroi'ighly sand the interiorof the inverted mold.

The chains 37 pass around sprockets 372L mounted upon a vshaft 38'3 andthese chains passing around the sprockets 37a are carried down through asuitable guide 37b under the vsand bo-X 38. Moi'inte'd upon the shaft38B there are also lsprockets 38A for driving the 'chains which feed the'inverted and sanded mold into the mold reverser 40 which is mountedupon the shaft 2O and which has the oppositely disposed compartments 40binto which the-inverted mold is y introduced and from which it isejected after it has been reversed and in connection with this'rmoldreverser I employ an ejector rod 40'@ carrying the finger at the outerend, this rod y4,0c working through the shaft l2O and itis obvious that,as the mold is carried across the sander and fed into one of thecompartments 40h, the mold which is in the opposite compartment 4Gb willbe ejected therefrom and transferred te the endless chains 39 whichtravel also around sprockets 39a mounted upon a shaft 41 which alsocarries aV sprocket 41a around which travels a chain 41b which travelsalso around a sprocket 41'C mounted upon the end of the pug rmill kshaft42.

As the mold s carried along the upper flights of the endlesschains 39,it is lifted i'ipvvardly by 'the mold lifter 43 carried 'at the end of arocker arm 44 mounted upon a rock shaft 44a and having a rocker arm 44hAcarrying a roll-er which iis engaged by the cam 44c mounted upon theshaft 41 andthe arm 44 also has an .extension 44d from which issuspended a weight 44e so 'that between the cam and the weight the moldlifter 43 will be moved vertically upwardly and maintained in properrelation through the medium of the parallel link rod 4,3a pivot allyconnectedto the mold vlifter 43 and i'dly connected 'to the rock shaft43h. The mold is llifted upwardly into line withV a horizontally movablepusher 45 which pushes the same horizontally beneath the die of Vthe pugmill.

The mold pusher 45 travels between the guide rolls 45'"L and is actuatedby a rocker arm 45h carried by a rock shaft 45 mounted upon the frame ofthe pug mill and having a crank arm 45d at its vouter end which isconnected to a pi'tman 45e worked from the crank or rocker arm 45foperated from the pug mill. The shaft 42 is constantly rotating andconsequently the shaft 41.

The shaft 24 -is also constantlyprotating but the shaft 21 makes only ahalf revolution at a time and this I accomplish by arranging upon oneend of the shaft 24 a sprocket 47 varound which travels a chain 48 whichin turn operates a sprocket 49 mounted upon the end of the shaft 21. Thesprocket 47 is loose upon. the shaft 24. Rigi'dly connected to thesli-aft 24, however, is a bifurcated arm 50 between which is 'pivot'ed apawl 51, this pawl 51 having a n lin-ger 51l and the arm 50k is providedwith a finger 50al in line with the finger 51a and between the fingers5()il and v51a I arrange a coil spring 52.

The sprocket carries two lugs 53 spaced 180 apart as most clearly shownin Figs. l5 and 16 and when the shaft is rotating in 'the directionindicated the lateral linger 51b of the pawl 51 contacts with the lug 53and carries the sprocket around until the end of the pawl 51 comes incontact with a roller 54 journaled upon a stud projecting laterally fromthe frame and when the pawl rides over the roller 5,4-, the laterallyprojecting iin-ger 51b is thrown out of disengagement and the arm withits pawl continues around until the next lug 53 is picked up and theoperation is continued as previously described.

This causes the shaft 24 to impart an intermittent motion to thesprocket 47 and this sprocket in 'turn imparts the intermittent motionto the sprocket 49 through the medium of thechain 48 and inl this mannerthe inverter is given a half 'rotation at the proper determined time. Y

Thetappets 29hl are mounted upon a shaft 229i which shaft has a sprocket'29k at its outer end around which travels the sprocket chain 291 whichreceives its power from the sprocket 29m mounted upon the end of theshaft 34.v

Upon one end of 'the shaft 21 there is arranged a brake 'drum l55 uponwhich bears a brake band 56 fastened at 56ste the frame andV carrying aweight 561 at its opposite end.v this brake Jdrum and band serving tohold the inverter in its proper positionl when at rest. The moldreverser 40 which is mounted en the shaft sois also intended to
